I've taken the "Flowchart" palette and made it a document. From there, I created a "Type" custom property for the nodes and assigned about half of the shapes a value. (Start, end, message, decision, etc). However when I try to re-integrate the document into the palette the property values have reverted back to the default values for all the shapes. The colours I've set for the nodes have remained. (Which is sort of a moot point because I have my properties manager assign node colours based on the data "Type" values.)
